Application filed July 18,

and effective attachment which will cause the sound box and needle to beautomatically swung over into its initialposition when it has reachedthe end of the record.

A further object is todevise a repeating device which can be adjusted towork with records of different sizes and a still further object is todevise a repeating dGVlCGWhlCh will be silent in operation.

My invention consists of a repeating device constructed and arranged allas, here1n after more particularly described and illustrated in theaccompanying drawing in which I Fig. 1 represents a plan view of therecord table, sound box'and tone arm showing my device applied thereto.

Fig. 2 is a side elevation thereof showing the'needle engaging therecord and a portion of my device mounted on the sound box in theinoperative position, and Fig. 3 is a similar view to Figure 2 showing aportion of my device on the sound box in the operative position.

Like characters of reference indicate corresponding parts in thedilferent views.

1 is the record turntable/to which is removably secured the usualcentral spindle 2 adapted to be rotated in the usual manner.

3 is the sound box. 54 is the tone arm. 5 is the annular'plat'e inthe-case of the gramophone through which the tone arm 4: extends.

51 is a bracket member suitably secured to the back face of the soundbox and having pivoted to its lower end the arm 6 upon. the free end ofwhich is journalled the wheel 7 which is preferably rubber-tired. 8 is ashoulder on the upper end of the arm 6 adapted to engage a correspondingshoulder 9 on the lower end of the bracket member 51 when the arm isswung into the position illustrated in Figure 3.

10 is a spring secured at one-end to the bracket 51 and at the other endto the arm 1922.- Serial No. 575,792.

6. 11 is a projection .on the free end of the arm 6.

12 is the needle mounted in the usual man- 7 ner in the socket 13 on thesound box.

1 1 is a hood member adapted. to extend over the spindle 2 above therecord 15 and.

to be secured thereto by means of the setscrew 16. 17 is an armextending transversely through the hood 14 above the spindle 2 andadaptedto be adjustably secured in position therein by means-of thesetscrew 18. I

19 is an arm adjustably secured at one end to the plate5 by means of theheaded stud 20 on such plate which extends through a slot 21 in the arm19. 22 is a thumb screw journalled in the-bearing 23 on the top'of themachineand held against-displacement by the collars-2 1. 25 is a lug on'the held end of the arm 19 said lug being provided with the threadedorifice 26 adapted to receive'the screw 22. The free end of-the arm-isbent inwardly towards the spindle 2 -and provided with a hooked. member27 pivoted thereto, one endof the hooked member 27 being provided withthe buffer 28' andga spring 29 extending between the arm 19 and thhooked member 27 for normally holding the same in the required position.1

My device operates as follows:

When the record is placed onthe turntable and the latter rotatedthesound box the record is reached, when upon the" arm travels acrossthe same in an inward direc- -t1on' 1n the usual. manner until the endof such arm will strike the-projection 11 on-the arm 6, causing'such armand' wheel'7 to be swung downwardly into the position illustrated inFigure 3 wherein the wheel 7 will engage the record 15 and the needlewill be raised off such record. Owing to centrifugal force the sound boxwhen supported on the wheel which engages the record will be swung toits outermost position] wherein a buffer 30, provided on theforwa'rdlface of the sound-box,willengage the buffer28, thus F [swingingthe hooked end of the hooked member 27 into engagement with the arm 6swinging the latter into the inoperative position illustrated in Figure2. The spring 10, which is distended when the arm 6 is moved into theposition illustrated in Figure 3, will restore the arm to the positionillustrated in Figure 2 when such arm is moved by the hooked member overthe vertical centre linethus allowing the sound box to drop down untilthe needle engages the record. On desiring to adjust thev arm 19 to suitrecords of different sizes, it is merely necessary to rotate the thumbscrew 22, which moves the arm through the medium of the lug 25 thereoninto which the screw is threaded.

From the above description it will be seen that I have devised a simpleand effective gramophone repeating device which can be readily appliedto existing gramophones and which will be positive in use and moreovercan be adjusted to operate on records of different' sizes.

lVhat I claim as my invention is.

1. In a gr'amophone' repeating device, the

combination with the sound box and record,

of a bracket secured to the sound box, an arm pivotally mounted on thebracket, a wheel oi'irnalled' onthe free end of the arm, the wheelengaging the record upon the arm being swung into the operative positionand elevating the sound box with the consequent disengagement of theneedle from the record, a shoul der'on the bracket and a shoulder on thearm engaging each other upon the arm being swung into the operativeposition.

2. In' a gramophone repeating device, the combination with the sound boxand record, of a bracket secured to the sound box, an arm pivotallymounted on the bracket, a wheel journal'led on the free endof the arm,the

wheel engaging'the record upon the arm being swung into the operativeposition and elevating the sound box with the consequent disengagementof the needle from the record, a shoulder on the bracket and a shoulderon the arm engaging each other uponthe a rm' beingswungi nto theoperative position and a spring secured to the bracket and its other endsecured to the arm for normally retaining it in the upper or inoperativeposition.

3". In a gramophone repeating device, the combination with the sound boxand record, of at swin able arm pivoted to the sound box, a rotatabIemember on the free end of said swingable arm adapted to engage therecord upon being. thrown into the operative position and lift theneedle out of engagement therewith by raising the sound box, aprojectifon on the arm, means engaging the projeetion torswingingthe arminto the operative position andmeans engaging the arm for swingingit-into the inoperative position. 4. Ina gramophone repeating device,the

member engaging the arm. upon the sound box reaching the outer limit ofits run.

5. In a gramophone repeating device, the combination with the sound box,record turn table spindle and record, of a swingable arm pivoted to thesound box, a rotatable memher on the free end of said swingable armadapted to engage the record upon being thrown into the operativeposition and lift the needle out of engagement therewith by raising thesound box, a projection on the arm, an adjustable arm on the record turntable spindle adapted to engage the projection upon the sound boxreaching the inner end of its run and a suitably supported adjust-ablehook member engaging the arm I upon the sound box reaching the outerhm1t of its run.

6. In a gramophone repeating dev1ce,- the combination with the soundbox, record turn table spindle and record, of needle disengaging meansand a hood adapted to be secured to the top of the record turn tablespindle. an arm adjustably secured to the hood adapted to engage theneedle disengaging means for throwing the same into the operativeposition and an adjustably mounted arm having a hook shaped memberadapted to engage the needle disengaging means and throwing it into theinoperative position, a buffer on the sound box adapted to engage thebuffer on the hook member for actuating the same.

7. In a gramophone repeating device, the combination with the sound box,record turn table spindle and record, of needle disengaging means on thesound box, a buffer on the sound box, an adjustable arm, a spring-heldhook member mounted on the adjustable arm, a buffer on the hook member,said buffer on the sound box adapted to engage therewith.
